The Subrogation Strategist

In City of Oroville v. Superior Court, 446 P.3d 304 (Cal. 2019), the Supreme Court of California considered whether the City of Oroville (City) was liable to a dental practice for inverse condemnation damages associated with a sewer backup. The court held that in order to establish inverse condemnation against a public entity, a property owner must show that an inherent risk in the public improvement was a substantial cause of the damage. Since the dental practice did not have a code-required backwater valve — which would have prevented or minimized this loss — the court found that the city was not liable because the sewage system was not a substantial cause of the loss.
